You need to use a gauge to figure out how mach is in your tires
Answers
Explanation:
Tire maintenance is one of the most important things you can do for your car from a safety and cost standpoint. The easiest way to care for your tires is both quick and inexpensive: maintain the correct tire pressure.
Driving on under-inflated tires is one of the biggest causes of tire failure, according to the National Highway Traffic Safety Administration, and not having enough air in your tires present many other problems. They wear out more rapidly, handle poorly and reduce fuel efficiency. In addition, over-inflated tires are more susceptible to damage from road irregularities, and this also creates a bumpier ride. Overfilling your tires is just as dangerous as under-filling them, so it’s important you know what is recommended for your vehicle.
How to check tire pressure
Knowing how to check tire pressure is critical to your safety and keeping your tires in good working order.
Use a tire pressure gauge
When it comes to choosing a gauge, you typically have 3 options:
Pen-type pressure gauges – Have a ruler-like rod that slides in and out of a sleeve to measure air pressure
Dial pressure gauges – Feature a numbered dial with a watch-like hand
Digital pressure gauges – Display numbers on a digital screen
Put the pressure gauge into the valve stem, making sure the gauge is evenly and firmly pressed onto the stem. If using a pen-style gauge, read the number on the rod that pops out of the sleeve. Read dial pressure gauges like you would a watch with one hand. With a digital pressure gauge, simply read the number on the screen. Don’t check your tire pressure more than once, since air can escape through the valve stem on subsequent readings.
